FM/UL Approved Fire Fighting Parts - Two Grooved End Coupling
Product Description
Feature: Premium Ductile Iron Grooved Coupling
1) Material: High-grade Ductile Iron ASTM
2) Reducing installation costs significantly
This advanced coupling is expertly crafted for pipes under moderate pressure. It permits controlled angular, linear, and rotational movements at each joint, while offering the tremendous benefits of expansion, contraction, and deflection. It adeptly manages uneven laying surfaces, and compensates for movement due to thermal fluctuations, settling, seismic effects, or other external factors.
